New in this release

As a security measure, if a git repository redirected you to a new URL, DiffPlug would refuse to disclose your password to the new URL and instead give an error. This error now includes a one-click "update this repository URL" to improve the workflow.

Fixed in this release

Fixed a parsing warning related to some stateflow transitions which crossed through subcharts.

Fixed a bug when accessing git repositories at the entity console without a trailing slash.

Fixed a bug where git repository credentials would sometimes need to be entered more than once.

The long wait for DiffPlug 2 is finally over! DiffPlug 2 streamlines the features from DiffPlug 1, and allows us to explore new capabilities that were impossible with DiffPlug 1.

DiffPlug 2 does not need to be installed, you can run it from any folder, and you can run it in parallel with an existing 1.x install without breaking it.

Many of the changes in DiffPlug 2 are about reorganizing DiffPlug 1's features, you can get an overview of them over at migrating from 1.x to 2.x. The list of changes below only covers new features and deprecated features - it doesn't include all the streamlining and simplification that happened between 1 and 2.

Improved Simulink support

3-way diff is now possible for the first time in DiffPlug

DiffPlug now supports MATLAB® R11 through R2019a, compared to just R2008a through R2017a for 1.8.10

Note: support for R11 through R2008b is provisional, full compatibility is guaranteed only for R2009a forward

Opening a Simulink file now takes half as much memory than in DiffPlug 1.8.10

Diffing two Simulink files now takes 17x less memory than in DiffPlug 1.8.10

The quality of Simulink diffs has also been improved dramatically

This feature has not yet been exposed to users, but it is now also possible for DiffPlug to modify a Simulink model. This will allow full merge in a future release.

Temporarily removed, but coming back

There are a few features that we were not able to include in DiffPlug 2.0, but they will definitely return in future versions of DiffPlug.

editing text files (currently view-only)

exportable Simulink diff report

archive decompression

Synergy CM support

Amazon S3 support

Permanently removed

32-bit operating systems

The last version of MATLAB to support a 32-bit operating system was R2015b. Many of the software systems that DiffPlug is built on top of have announced end-of-life for 32-bit operating systems.

Windows XP

DiffPlug uses many of the same libraries as the Eclipse Java IDE. The latest release of Eclipse has dropped support for Windows XP. The minimum required version is now Windows Vista.

Subversion

Git's dominance in the version-control industry makes it difficult to justify maintenance and upkeep on our subversion integration.

If the output file is output.xml, there will now be a folder output.xml_images which contains a series of 1:1 scale png images.

Each changed block will have xml attributes left_img and right_img, which will point to the filename of an image which highlights that particular change.

Each diagram which contains changes will have xml attributes left_diagram_img and right_diagram_img, which will point to the filename of an image which contains all the changes of that particular subsystem.

Normally, the XML report format only contains xml elements for items which have been changed or added. In XML_WITH_IMAGES mode, a subsystem which is itself identical, but contains changed children, will appear in the XML document as a nested element, and will have left_diagram_img and right_diagram_img properties.

Simulink subsystems and subcharts can now be opened in a new tab.

When moving up a subsystem, the previously displayed subsystem is now highlighted briefly.
